IMPROVEMENT IN T-COUPLINGS FOR PIPES.

\ Specification forming part of Letters Patent N 0. 172,1] 7, datedJanuary 11, 1876; application filed December 9, 1875.

Figure 1 is a central longitudinal section of' my i in provement. a; 00,Fig. l.

Similar letters indicate corresponding parts. This invention relates toT-co'uplings for pipes; and consists in the arrangement therein ot' adiaphragm stretching across the interior, beginning at one side of thecoupling, near the place where the middle socket intersects the same,and extending out gradually toward the center of the coupling oppositeor in front of the mouth of the middle socket, and terminat- Fig. 2 is across-section at W ing at a point near to or past the opposite side ofthe middle socket.

My invention enables me to divide a current of steam or other fluid bymeans of the diaphragm, so as to insure the entrance into the middlesocket and its connections of a portion of the current which has enteredthe coupling, which result is only obtained in the case of ordinaryT-couplings after the pipes and connections which are in the direct lineof the coupling are filled, until which time the current naturally flowspast the lateral socket, instead of passing through it and filling itsconnections. This result of my invention renders it of value in steamand hot-water radiators, since by means thereof the lateral connectionswill. receive a due share of the current which enters the receiving endof the coupling. v

My invention is also of great advantage in leading off condensed water,since the water coming into the coupling through one of the end socketsis prevented from interfering with or overpowering a current coming fromthe middle socket, or vice versa.

The letter A designates a T-coupling, having the usual end sockets B Band a middle socket, G. D is a diaphragm cast in the interior of thecoupling, extending from side to side, beginning at or near one side ofthe middle socket, and inclining or curving out gradually toward thecenter of the coupling, in front of the mouth of the middle socket.

The diaphragm extends forward into the coupling far enough to secure thedesired action and result, and in this example its length is a littlegreater than the Width of the middle socket-opening.

It is obvious that byjmeans of my invention a current of steam enteringthe coupling in the direction of the arrow l-that is to say, from theleft-hand sidewill be divided by the diaphragm, a part being directedinto the middle socket, and the residue being left to piss through thecoupling in the direction in which it entered it. Furthermore, if acurrent of condensed water flows into the coupling in the direction ofarrow 2that is to say, from the right-hand side through the end socketorthe middle socket, or boththe diaphragm will guide it in such a mannerthat the currents will'enter the coupling without hinderance orinterference from each other, and neither current willreact upon thecurrent coming through another part of the coupling.

My invention is applicable to couplings where more than one lateralsocket are employed; but where more than one are employed in connectionwith my diaphragm, the diaphragins are not extended out so near thecenter line of the coupling, but room is left between the diaphragms foracentral passage in the line of the coupling.

What I claim as new, and desire to secure by Letters Patent, is

A diaphragm combined with a T-coupling for pipes, substantially as abovedescribed.

In testimony that 1 claim the foregoing I have hereunto set my hand andseal this 7 th day of December, 1875. p THOMAS P. HARDY. [L.S.
